Dr. Pamela Lillian Isley is a plant-human hybrid, the result of a scientific experiment gone wrong known as Poison Ivy. Ivy's known goal is to wipe out all of humanity and cleanse the world of pollution. She developed a variety of powers including pheromone seduction, plant manipulation and mind control, as well as various toxic based abilities.
Poison Ivy does not actually appear in the game, but she, or rather, her identity of Pamela Isley, was alluded to in the story DLC Cold, Cold Heart, where she was implied to have visited GothCorp sometime between the main story and Mr. Freeze's takeover of GothCorp.
Post Arkham Origins
Her crimes have become more ecologically focused as she has increasingly abandoned her human side, identifying more with the natural world. Her unique brand of eco-terrorism often puts her into conflict with Batman, whose iron will usually protect him from her seductive powers.
Height = 5' 8"
Weight = 115 pounds
Apparently she prefers to be all natural when in incarceration, with her plants and barely covers herself; only keeping one or two buttons on her shirt buttoned and wearing foliage panties, taking on a "naked goddess" persona.
Batman, whilst searching for the Warden in the Penitentiary of Arkham Asylum, comes across Poison Ivy in her cell. Sensing that her plants were in pain, Ivy pleads desperately with Batman to save them. Not sharing her concern, and knowing full well what kind of havoc Ivy could wreak if released, Batman disregards her plea, leaves her in her cell, and continues looking for the Warden. Soon after, Harley Quinn also makes her way past Ivy and Ivy begs her to let her out so she can rescue her "babies." At first, Harley refuses because Ivy isn't on Joker's 'party list;' however, she gives in rather quickly and unlocks the cell door, leaving Poison Ivy free to make her way to the Botanical Gardens.
After discovering Joker's secret lab in the Gardens, Batman goes to Ivy, whose plants had been used to help create the venom. Ivy refuses to help at first, deciding instead to let the Joker "have his fun," but eventually agrees after Batman threatens to destroy her plants if she doesn't cooperate. Ivy then tells Batman that the spores needed to create the anti-venom are produced by a plant located deep in Killer Croc's lair. Before leaving, Batman instructs Ivy to return to her cell or he'll be back, to which Ivy replies that she'll be waiting for him.
The Joker subsequently injects Ivy with the new Titan formula. Instead of creating a "monster plant" as the Joker expected, Ivy remains the same on the outside (although with glowing green irises) but gains an enhancement to her chrolokinetic abilities, inducing rapid growth and evolution amongst her plants, even among the newly mutated plants were a species that produced glowing airborne toxic spores (though it should be noted that Batman said that Ivy used a similar species of plants during an attack on Gotham a year ago).
Ivy takes the opportunity to take over the entire island with her newly mutated plants, vowing to kill Batman and eventually, the Joker himself, much to his delight; looking forward to the coming battle. Batman eventually returns to the Gardens with the anti-venom formula, where Ivy beckoned Batman to come to her lair. Along the way, Batman was attacked by two security guards under Ivy's control, being forced to defeat them both. Batman attempted to inject Ivy's plants with the anti-venom before being stopped by an attacking Ivy, who forced him to contend with more Arkham guards infected by her mind-controlling plant spores, including William North and Eddie Burlow. The two engaged in a long and strenuous fight resulting in Ivy's defeat. After the Joker's defeat, Ivy was taken back to her cell by the Arkham staff.
After Arkham
Poison Ivy settling nicely in Gotham Central Park her new home in Arkham City.
After being given an overdose of Titan by the Joker, and her attempted escape and mind-control of the Asylum guards during Arkham Island Lockdown, Poison Ivy was left to die in her airtight cell by Warden Sharp, who blamed her for the mass destruction of Arkham Island.
As her health started to decline, Ivy prayed for salvation; which came in the form of a priest, who was unknowingly covered in pollen from the trees near his church. As he performed the last rites, Ivy manipulated the pollen spores into an antidote that worked in harmony with the unique, natural toxins in her blood, and to the amazement of the priest, she began a full recovery.
Furious, Sharp locked her in a Biological containment unit and arranged for her to be one of the first criminals sent to Arkham City which was intercepted by Catwoman who freed her.
Catwoman explained to Batman that while she was procuring stolen goods and other items around Arkham City, she rescued Poison Ivy from TYGER custody, then dropped her off in Gotham Central Park. It seems that this was part of a plan by Catwoman to gather powerful allies for future venues in Arkham City. Catwoman promises to water Ivy's plants, a promise she breaks and leads to the events between her and Ivy in Batman: Arkham City.
During his transfer to Arkham City, The Riddler hired Poison Ivy to help him escape his holding cell so he could head to his new hideout.
Ivy briefly appeared later in Two-Face's trial against the Joker as a jury member, where she testified against him, blaming him for her poisoning, the destruction of Arkham Asylum and the attempted murder of Harley Quinn.
"Well what do you have here? Weird, out of place plants... check. Mindless, hypnotized henchmen... check. The oh so subtle odor of rotting pumpkins... check. Looks like I've found the entrance to Ivy's lair."
Poison Ivy's presence in Arkham City comes with the Catwoman online pass; she appears in two out of Catwoman's four episodes.
While plotting to break into Hugo Strange's Confiscated Goods Vault, Catwoman decides to ask Ivy for assistance, saying she prefers a woman's touch. She heads into Ivy's Lair, an old hotel, full of plants and hypnotized thugs, where Ivy is shown to be angry with her. Ivy attacks Catwoman with the hypnotized thugs and heat-seeking spores, which Ivy has prepared for months to rid Arkham of "flesh-sacks" and replace them with spores; despite Catwoman explaining that she "just wants to talk". When all the thugs have been defeated, Ivy uses one of her vines to attack and hang Catwoman upside down, where she expresses her anger over the death of her plants, which Catwoman promised to look after, stating that the only remaining one of those flowers is within Hugo's vault.
Catwoman offers to retrieve the flower for Ivy if she creates a route for her to get into the vault. Ivy agrees reluctantly, knowing that Catwoman can get the plant for her. Catwoman shows some confusion at first, as if Ivy will do it or not. Later, is shown that Poison Ivy has used her vines to create an underground tunnel to the vault. Once Catwoman is inside the vault, she spots Ivy's plant, and throws it on the floor and kills it as revenge for Ivy attacking her, and distant screams of Ivy can be heard. When (or if) Catwoman decides to return to see Ivy, she blames the death of the plant on Strange. Filled with hatred, Ivy states she will soon take her revenge on Hugo Strange and all humanity.
She was eventually kidnapped, alongside Catwoman, The Carpenter, and Vicki Vale by the Mad Hatter, and brainwashed into believing they are specific characters from Alice in Wonderland (in Poison Ivy's case, the Red Queen/Queen of Hearts), and later ended up fighting Batman alongside the others before Batman removed the effects of her brainwashing.
Poison Ivy was offered a chance by Scarecrow to take Gotham City and rid themselves of Batman once and for all. Having refused his offer, Scarecrow took Ivy prisoner and brought to his penthouse in Chinatown as a test subject for his new fear gas. Fortunately for Ivy, the gas didn't affect her and she was taken into custody by Batman once he took down Scarecrow's goons. Ivy was taken to the GCPD in the Batmobile and placed in an isolation chamber.
Later, Batman realized he needed a way to counter the effects of Scarecrow's new toxin and that Ivy was the only one that showed a natural immunity to it. Heading back to the GCPD, Ivy revealed to Batman that she created a spore to counter the effects of Crane's toxin which she used on a molecular level. She also theorized that she could make the whole city immune as well, but she couldn't produce enough on her own. The only way for her to do so would be at Gotham's Botanical Gardens which was where Batman took her. Ivy began manipulating the only living large plant in the gardens with the help of the Batmobile's ground penetrating sonar emitter. Once the plant was brought back to life, the Arkham Knight's militia began attacking it, leading to Batman having to defend Ivy while she worked to produce the spore.
When the Knight sent more troops and tanks to attack the Botanical Gardens, Ivy utilized the plant she was in and Batman used the Batmobile to take on more tanks that came into the vicinity of the gardens. After taking out the drones, the militia sent Cobra tanks to attack them, which Batman took down on his own. Realizing Ivy wasn't safe, Batman tried bringing her back to the GCPD only to be alerted by Alfred on the Cloudburst which went off, sending Crane's fear toxin throughout Gotham. The toxin actually caused her plants to begin dying, so she stayed with them while Batman went to find Simon Staggs in hopes of destroying the cloud of fear toxins.
After Batman dealt with the cloudburst and the Arkham Knight, Batman headed for the gardens once more to check on Ivy. When he arrived, he found a weak Ivy giving one last burst of power she had into the plant, restoring it and absorbing Crane's toxins into herself. Batman held her in his arms before she dissolved into particles, thus dying from the effects of the toxins. After she dissolved, the plants she used, cleansed Gotham of all the toxins.

Poison Ivy's patient interview tapes.
Tape One
(Patient Interview #41; November 12)
Dr. Stephen Kellerman: "Patient interview. Pamela Lillian Isley. November 12, 11:33 AM. Good morning, Pamela. How are you today?"
Poison Ivy: "Fine. Today is a special day."
Dr. Stephen Kellerman: "What do you mean?"
Poison Ivy: "This is the anniversary of my new life, when I found my true self, my destiny."
Dr. Stephen Kellerman: "Are you referring to the event with Dr. Woodrue?"
Poison Ivy: "Yes, what else? Of course, at the time I thought Jason had poisoned me, but in retrospect he did me a huge favor."
Dr. Stephen Kellerman: "And why do you believe what he did has... helped you?"
Poison Ivy: "He showed me the bigger world. A world I should protect. Of course, my first offer was rejected."
Dr. Stephen Kellerman: "Offer? You tried to kill everyone in Gotham."
Poison Ivy: "Well, sometimes you need to prune back hard in order to make something flourish."
Tape Two
(Patient Interview #42; November 13)
Dr. Stephen Kellerman: "Patient interview. Pamela Lillian Isley. November 14, 10:21 AM. Hello, Pamela. Today I'd like to go back to something you said in our last conversation."
Poison Ivy: "Ask me anything you like."
Dr. Stephen Kellerman: "You said your first offer to help Gotham was rejected. How can you possibly believe that?"
Poison Ivy: "What do you mean?"
Dr. Stephen Kellerman: "You released thousands of poisonous spores into Gotham, killed hundreds of people. How does that help anybody?"
Poison Ivy: "I'm not interested in bodies, Doctor. Horrible fleshy sacks walking around destroying my poor babies with their greed and arrogance."
Dr. Stephen Kellerman: "But aren't you one of those fleshy sacks? You're a... were a doctor too. How can you turn your back on us?"
Poison Ivy: "Quite easily, as it happens, but not you....Stephen. You're different. I feel we have a connection."
Dr. Stephen Kellerman: "Really? You do?" (Dr. Kellerman is slowly being seduced by Ivy's mind control and is falling under her spell)
Poison Ivy: "Of course.."
Tape Three
(Patient Interview #43; November 15)
Dr. Stephen Kellerman: "Pamela! I got you what you asked for. Do you like it?"
Poison Ivy: "Oh yes, Stephen, I love it. Such a beautiful flower. Do you mind it if i keep it?"
Dr. Stephen Kellerman: "Oh no, Pamela. I can't leave it. It's against all the rules. I'll just bring it and show it to you when I visit."
Poison Ivy: "But it's me, Stephen. I get so lonely on my own. You wouldn't want me to be lonely, would you?"
Dr. Stephen Kellerman: "No, of course not. Keep it. Just don't let anyone see it. Really. No one."
Poison Ivy: "You can trust me, Stephen. Thank you. Now give me a kiss."
Dr. Stephen Kellerman: "I can't... people will see."
Poison Ivy: "No one's watching. What is wrong with you? Don't you love me? Call me Ivy."
Dr. Stephen Kellerman: "Of course I love you."
Tape Four
(Patient Interrogation # 1; November 17)
Warden Quincy Sharp: Where is Doctor Kellerman?
Pamela Isley: How should I know, Warden? It does seem careless of you to have lost him.
Warden Quincy Sharp: I have no time for your games Miss Isley. Tell me where you have him. We have security footage of you and him leaving your cell last night.
Pamela Isley: So?
Warden Quincy Sharp: Do I need to spell it out? We know you hypnotized him, or whatever it is that you do. We know he took you somewhere, but conveniently, security cameras across the island were mysteriously covered by leaves and flowers at 3 AM. Now tell me where he is!
Pamela Isley: I’m not saying a word unless you do exactly what I tell you to do.
Tape Five
(Patient Interrogation # 3; November 18)
Warden Quincy Sharp: We found him. No thanks to you. The poor man could have died.
Pamela Isley: So?
Warden Quincy Sharp: He has a wife. A child.
Pamela Isley: As do the plants he tramples underfoot. The spores he breathes in and destroys have children. Why does he deserve anything more than them? You people ignore what is happening in front of your eyes.
Warden Quincy Sharp: I refuse to put the welfare of plants before the welfare of people.
Pamela Isley: And that is why you will lose. There's more happening than you know, Warden. It’s all connected.
Yet another patient whose treatment is complicated by a bizarre medical condition, Isley has a modified genetic code that incorporates plant DNA and renders her physically toxic to others. She is essentially deeply antisocial, believing herself to be not only inhuman but superior to others; this diagnosis is tied into her hypersexuality, which takes the form of a constant attempt to seduce others to do her bidding. She also displays a narcisstic belief in her role as the protector of the entire natural world.
Additional Notes
Oddly, Isley is another former doctor who is now an inmate.
She seems resentful during our treatment sessions; I believe the fact I'm a woman frustrates her erotomania. She desperately believes that all male residents of Arkham are at least partly in love with her.
I've been looking through her old research papers, many of which were never published. There is some fascinating work there...

I've spent weeks perfecting the toxins that will destroy your pathetic meat sack of a body.
A billion micro-organisms will enter your bloodstream. Spores will grow, replacing the blood in your veins, and when I'm done, your flesh will be replaced with bark.
You can't outrun nature, Selina. My spores will fill your lungs and kill you from within.
Do you really think you can beat mother nature?

Trivia
Poison Ivy concept art by artist Carlos D'Anda
Pamela Isley's I.D. badge.
In Dr. Young's notes, she has seen only her own profile, due to the fact that her picture was the only picture to have her genetics (lips) on it.
The vines on her body were intended to resemble body tattoos.
Tasia Valenza, who voiced Ivy in the game, also voiced Martha Wayne.
Pamela Isley's ID badge at GothCorp during the Heart of Ice DLC story was most likely a reference to the teamup between Poison Ivy and Mr. Freeze in Batman & Robin.
It appears that her powers have grown since Arkham Asylum, given her claims to have perfected new pheromone formulas, a reference to her former status as a scientist.
Poison Ivy is the only character that Batman does not interact with, as he cannot enter the building she is in. However, it is likely he was aware of her location, as there are large plants covering the area.
It is mentioned in a side story that Ivy was able to cure herself of Titan poisoning via spores on the clothes of a priest who visited her cell. Despite this, Batman makes no attempt to ask Ivy to manufacture a cure for him, likely because she is more hostile towards him than Mr. Freeze.
Ivy seems to already have a friendship with Catwoman before the game, but she became angry at her because Catwoman forgot to water plants Ivy had given her, and, as a result, the plants died. Although Catwoman tries to smooth things over, Ivy only begrudgingly helps her, and is still mad at her by the end of the game.
Batman Arkham City Lockdown - Poison Ivy
Poison Ivy Lockdown
Both Catwoman and Ivy lose their possessions to Hugo Strange and have them permanently lost during the events of Protocol 10.
Ivy appears in Batman: Arkham City Lockdown in the Business District level, Ivy's taking over the Gotham Police force with the usage of her toxic pheromones and turns them against Batman. After taking care of the police Batman arrives at The Solomon Wayne courthouse to find Ivy awaiting him with Robin who she also had under her control. Batman engages in an intense battle against his sidekick and ultimately wins. Ivy admits defeat and surrenders to Batman willingly. Although she attempts to kiss him as a means to escape but Batman outsmarts her and handcuffs her away back to Arkham.
Unlike the other voice cast, Tasia Valenza does not reprise her role for Arkham City Lockdown. Instead, Amy Carle assumes the role of Poison Ivy.
When Batman talks with Officer Boulden in the GCPD, he can learn that he is attracted to her.
Although she apparently dies, if the player goes back to the place of her death, they will see a flower growing from Ivy's clothes.
